- <title>Datalagringsdirektivet gjør at Oslo Høyre og Arbeiderparti ikke får min stemme i år</title>

- <description><p>I 2011 raderte et stortingsflertall bestående av Høyre og
-Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske
-folk. Det ble vedtatt at det skulle registreres og lagres i et halvt
-år hvor alle som bærer på en mobiltelefon befinner seg, hvem de
-snakker med og hvor lenge de snakket sammen. Det skal også
-registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost
-til, og hvilke nett-tjenere en besøkte. Saken er kjent som
-<a href="http://beta.holderdeord.no/issues/innfore-datalagringsdirektivet">Datalagringsdirektivet
-(DLD)</a>, og innebærer at alle innbyggerne og andre innenfor Norges
-grenser overvåkes døgnet rundt. Det ble i praksis innført brev og
-besøkskontroll av hele befolkningen. Rapporter fra de landene som
-allerede har innført slik total lagring av borgernes
-kommunikasjonsmønstre forteller at det ikke hjelper i
-kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre
-millioner, uten at det ser ut til å bidra positivt til politiets
-arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt
-på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen.
-Se mer på
-<a href="http://no.wikipedia.org/wiki/Datalagringsdirektivet">Wikipedia</a>
-og <a href="http://www.uhuru.biz/?cat=84">Jon Wessel-Aas</a>.</p>
-
-<p>Hva er problemet, tenkter du kanskje? Et åpenbart problem er at
-medienes kildevern i praksis blir radert ut. Den innsamlede
-informasjonen gjør det mulig å finne ut hvem som har snakket med
-journalister på telefon, SMS og epost, og hvem som har vært i nærheten
-av journalister så sant begge bar med seg en telefon. Et annet er at
-advokatvernet blir sterkt redusert, der politiet kan finne ut hvem
-som har snakket med en advokat når, eller vært i møter en med advokat.
-Et tredje er at svært personlig informasjon kan avledes fra hvilke
-nettsteder en har besøkt. Har en besøkt hivnorge.no,
-swingersnorge.com eller andre sider som kan brukes til avlede
-interesser som hører til privatsfæren, vil denne informasjonen være
-tilgjengelig takket være datalagringsdirektivet.</p>
-
-<p>De fleste partiene var mot, kun to partier stemte for. Høyre og
-Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har
-DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre
-fylkene). Det er dermed helt uaktuelt for meg å stemme på disse
-partiene. Her er oversikten over partienes valglister i Oslo, med
-informasjon om hvem som stemte hva i første DLD-votering i Stortinget,
-basert på informasjon fra mine venner i
-<a href="http://beta.holderdeord.no/votes/1301946411e">Holder de
-Ord</a> samt <a href="http://data.stortinget.no/">data.stortinget.no</a>.

+ <description><p>Microsoft have announced that Windows XP reaches its end of life
+2014-04-08, in 7 days. But there are heaps of machines still running
+Windows XP, and depending on Windows XP to run their applications, and
+upgrading will be expensive, both when it comes to money and when it
+comes to the amount of effort needed to migrate from Windows XP to a
+new operating system. Some obvious options (buy new a Windows
+machine, buy a MacOSX machine, install Linux on the existing machine)
+are already well known and covered elsewhere. Most of them involve
+leaving the user applications installed on Windows XP behind and
+trying out replacements or updated versions. In this blog post I want
+to mention one strange bird that allow people to keep the hardware and
+the existing Windows XP applications and run them on a free software
+operating system that is Windows XP compatible.</p>
+
+<p><a href="http://www.reactos.org/">ReactOS</a> is a free software
+operating system (GNU GPL licensed) working on providing a operating
+system that is binary compatible with Windows, able to run windows
+programs directly and to use Windows drivers for hardware directly.
+The project goal is for Windows user to keep their existing machines,
+drivers and software, and gain the advantages from user a operating
+system without usage limitations caused by non-free licensing. It is
+a Windows clone running directly on the hardware, so quite different
+from the approach taken by <a href="http://www.winehq.org/">the Wine
+project</a>, which make it possible to run Windows binaries on
+Linux.</p>
+
+<p>The ReactOS project share code with the Wine project, so most
+shared libraries available on Windows are already implemented already.
+There is also a software manager like the one we are used to on Linux,
+allowing the user to install free software applications with a simple
+click directly from the Internet. Check out the
+<a href="http://www.reactos.org/screenshots">screen shots on the
+project web site</a> for an idea what it look like (it looks just like
+Windows before metro).</p>
+
+<p>I do not use ReactOS myself, preferring Linux and Unix like
+operating systems. I've tested it, and it work fine in a virt-manager
+virtual machine. The browser, minesweeper, notepad etc is working
+fine as far as I can tell. Unfortunately, my main test application
+is the software included on a CD with the Lego Mindstorms NXT, which
+seem to install just fine from CD but fail to leave any binaries on
+the disk after the installation. So no luck with that test software.
+No idea why, but hope someone else figure out and fix the problem.
+I've tried the ReactOS Live ISO on a physical machine, and it seemed
+to work just fine. If you like Windows and want to keep running your
+old Windows binaries, check it out by
+<a href="http://www.reactos.org/download">downloading</a> the
+installation CD, the live CD or the preinstalled virtual machine
+image.</p>

- <description><p>The second wheezy based beta release of Debian Edu was wrapped up
-today, slightly delayed because of some bugs in the initial Windows
-integration fixes . This is the release announcement:</p>
-
-<p><strong>New features for Debian Edu 7.1+edu0~b1 released 2013-08-22</strong></p>
-
-<p>These are the release notes for Debian Edu / Skolelinux
-7.1+edu0~b1, based on Debian with codename "Wheezy".</p>
-
-<p><strong>About Debian Edu and Skolelinux</strong></p>
-
-<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
-Skolelinux</a>, is a Linux distribution based on Debian providing an
-out-of-the box environment of a completely configured school
-network. Immediately after installation a school server running all
-services needed for a school network is set up just waiting for users
-and machines being added via GOsa², a comfortable Web-UI. A netbooting
-environment is prepared using PXE, so after initial installation of
-the main server from CD or USB stick all other machines can be
-installed via the network. The provided school server provides LDAP
-database and Kerberos authentication service, centralized home
-directories, DHCP server, web proxy and many other services. The
-desktop contains
-<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
-than 60 educational software packages</a> and more are available from
-the Debian archive, and schools can choose between KDE, Gnome, LXDE
-and Xfce desktop environment.</p>
-
-<p>This is the sixth test release based on Debian Wheezy. Basically this
-is an updated and slightly improved version compared to the Squeeze
-release.</p>
-
-<p>ALERT: Alpha based installations should reinstall or downgrade the
-versions of gosa and libpam-mklocaluser to the ones used in this beta
-release. Both alpha and beta0 based installations should reinstall or
-deal with gosa.conf manually; there are two options: (1) Keep
-gosa.conf and edit this file as outlined
-<a href="http://lists.debian.org/debian-edu/2013/08/msg00127.html">on
-the mailing list</a>. (2) Accept the new version of gosa.conf and
-replace both contained admin password placeholders with the password
-hashes found in the old one (backup copy!). In both cases every user
-need to change their their password to make sure a password is set for
-CIFS access to their home directory.</p>
-
-<p><strong>Software updates</strong></p>
-
-<ul>
-
-<li>Added ssh askpass packages to default installation, to ensure ssh
- work also without a attached tty.</li>
-<li>Add the command-not-found package to the default installation to
- make it easier to figure out where to find missing command line
- tools. Please note, that the command 'update-command-not-found'
- has to be run as root to actually make it useful (internet access
- required).</li>
-
-</ul>
-
-<p><strong>Other changes</strong></p>
-
-<ul>
-
-<li>Adjusted the USB stick ISO image build to include every tool
-needed for desktop=xfce installations.</li>
-<li>Adjust thin-client-server task to work when installing from USB
-stick ISO image.</li>
-<li>Made new grub artwork (changed png from indexed to RGB format).</li>
-<li>Minor cleanup in the CUPS setup.</li>
-<li>Make sure that bootstrapping of the Samba domain really happens
- during installation of the main server and adjust SID handling to
- cope with this.</li>
-<li>Make Samba passwords changeable (again) via GOsa².</li>
-<li>Fix generation of LM and NT password hashes via GOsa² to avoid
- empty password hashes.</li>
-<li>Adapted Samba machine domain joining to latest change in the
- smbldap-tools Perl package, fixing bugs blocking Windows machines
- from joining the Samba domain.</li>
-
-</ul>
-
-<p><strong>Known issues</strong></p>
-
-<ul>
-
-<li>KDE fails to understand the wpad.dat file provided, causing it to
- not use the http proxy as it should.</li>
-<li>Chromium also fails to use the proxy when using the KDE desktop
- (using the KDE configuration).</li>

+ <description><p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
+keep gaining new users. Some weeks ago, a person showed up on IRC,
+<a href="irc://irc.debian.org/#debian-edu">#debian-edu</a>, with a
+wish to contribute, and I managed to get a interview with this great
+contributor Roger Marsal to learn more about his background.</p>
+
+<p><strong>Who are you, and how do you spend your days?</strong></p>
+
+<p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
+live in Barcelona, Spain. I've got a strong business background and I
+work as a patrimony manager and as a real estate agent. Additionally,
+I've co-founded a British based tech company that is nowadays on the
+last development phase of a new social networking concept.</p>
+
+<p>I'm a Linux enthusiast that started its journey with Ubuntu four years
+ago and have recently switched to Debian seeking rock solid stability
+and as a necessary step to gain expertise.</p>
+
+<p>In a nutshell, I spend my days working and learning as much as I
+can to face both my job, entrepreneur project and feed my Linux
+hunger.</p>
+
+<p><strong>How did you get in contact with the Skolelinux / Debian Edu
+project?</strong></p>
+
+<p>I discovered the <a href="http://www.ltsp.org/">LTSP</a> advantages
+with "Ubuntu 12.04 alternate install" and after a year of use I
+started looking for an alternative. Even though I highly value and
+respect the Ubuntu project, I thought it was necessary for me to
+change to a more robust and stable alternative. As far as I was using
+Debian on my personal laptop I thought it would be fine to install
+Debian and configure an LTSP server myself. Surprised, I discovered
+that the Debian project also supported a kind of Edubuntu equivalent,
+and after having some pain I obtained a Debian Edu network up and
+running. I just loved it.</p>
+
+<p><strong>What do you see as the advantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I found a main advantage in that, once you know "the tips and
+tricks", a new installation just works out of the box. It's the most
+complete alternative I've found to create an LTSP network. All the
+other distributions seems to be made of plastic, Debian Edu seems to
+be made of steel.</p>
+
+<p><strong>What do you see as the disadvantages of Skolelinux / Debian
+Edu?</strong></p>
+
+<p>I found two main disadvantages.</p>
+
+<p>I'm not an expert but I've got notions and I had to spent a considerable
+amount of time trying to bring up a standard network topology. I'm quite
+stubborn and I just worked until I did but I'm sure many people with few
+resources (not big schools, but academies for example) would have switched
+or dropped.</p>
+
+<p>It's amazing how such a complex system like Debian Edu has achieved
+this out-of-the-box state. Even though tweaking without breaking gets
+more difficult, as more factors have to be considered. This can
+discourage many people too.</p>
+
+<p><strong>Which free software do you use daily?</strong></p>
+
+<p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
+Virtualbox.</p>
+
+
+<p><strong>Which strategy do you believe is the right one to use to
+get schools to use free software?</strong></p>
+
+<p>I don't think there is a need for a particular strategy. The free
+attribute in both "freedom" and "no price" meanings is what will
+really bring free software to schools. In my experience I can think of
+the <a href="http://www.r-project.org/">"R" statistical language</a>; a
+few years a ago was an extremely nerd tool for university people.
+Today it's being increasingly used to teach statistics at many
+different level of studies. I believe free and open software will
+increasingly gain popularity, but I'm sure schools will be one of the
+first scenarios where this will happen.</p>

+ <description><p><a href="http://www.nuug.no/">Foreningen NUUG</a> melder i natt at
+NRK nå har bestemt seg for
+<a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
+den norske dokumentarfilmen om datalagringsdirektivet skal
+sendes</a> (se <a href="http://www.imdb.com/title/tt2832844/">IMDB</a>
+for detaljer om filmen) . Første visning blir på NRK2 mandag
+2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
+kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
+Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv. Som
+oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
+Aftenposten fra i går,
+<a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
+gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
+retten til privatliv og beskyttelsen av demokrati i Norge og resten
+verden, og helt riktig slår fast at det er vi i databransjen som
+sitter med nøkkelen til å gjøre noe med dette. Jeg har involvert meg
+i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
+og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
+forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
+hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
+gjenopprettet balansen.</p>
+
+<p>Jeg regner med at nettutgaven dukker opp på
+<a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
+side om filmen om datalagringsdirektivet</a> om fem dager. Hold et
+øye med siden, og tips venner og slekt om at de også bør se den.</p>

+ <description><p>Did you ever need to store logs or other files in a way that would
+allow it to be used as evidence in court, and needed a way to
+demonstrate without reasonable doubt that the file had not been
+changed since it was created? Or, did you ever need to document that
+a given document was received at some point in time, like some
+archived document or the answer to an exam, and not changed after it
+was received? The problem in these settings is to remove the need to
+trust yourself and your computers, while still being able to prove
+that a file is the same as it was at some given time in the past.</p>
+
+<p>A solution to these problems is to have a trusted third party
+"stamp" the document and verify that at some given time the document
+looked a given way. Such
+<a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service
+have been around for thousands of years, and its digital equivalent is
+called a
+<a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
+timestamping service</a>. <a href="http://www.ietf.org/">The Internet
+Engineering Task Force</a> standardised how such service could work a
+few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC
+3161</a>. The mechanism is simple. Create a hash of the file in
+question, send it to a trusted third party which add a time stamp to
+the hash and sign the result with its private key, and send back the
+signed hash + timestamp. Both email, FTP and HTTP can be used to
+request such signature, depending on what is provided by the service
+used. Anyone with the document and the signature can then verify that
+the document matches the signature by creating their own hash and
+checking the signature using the trusted third party public key.
+There are several commercial services around providing such
+timestamping. A quick search for
+"<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161
+service</a>" pointed me to at least
+<a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>,
+<a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo
+Vadis</a>,
+<a href="https://www.globalsign.com/timestamp-service/">Global Sign</a>
+and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global
+Trust Finder</a>. The system work as long as the private key of the
+trusted third party is not compromised.</p>
+
+<p>But as far as I can tell, there are very few public trusted
+timestamp services available for everyone. I've been looking for one
+for a while now. But yesterday I found one over at
+<a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches
+Forschungsnetz</a> mentioned in
+<a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a
+blog by David Müller</a>. I then found
+<a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a
+good recipe on how to use the service</a> over at the University of
+Greifswald.</p>
+
+<p><a href="http://www.openssl.org/">The OpenSSL library</a> contain
+both server and tools to use and set up your own signing service. See
+the ts(1SSL), tsget(1SSL) manual pages for more details. The
+following shell script demonstrate how to extract a signed timestamp
+for any file on the disk in a Debian environment:</p>
+
+<p><blockquote><pre>
+#!/bin/sh
+set -e
+url="http://zeitstempel.dfn.de"
+caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt"
+reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
+resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
+cafile=chain.txt
+if [ ! -f $cafile ] ; then
+ wget -O $cafile "$caurl"
+fi
+openssl ts -query -data "$1" -cert | tee "$reqfile" \
+ | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile"
+openssl ts -reply -in "$resfile" -text 1>&2
+openssl ts -verify -data "$1" -in "$resfile" -CAfile "$cafile" 1>&2
+base64 < "$resfile"
+rm "$reqfile" "$resfile"
+</pre></blockquote></p>
+
+<p>The argument to the script is the file to timestamp, and the output
+is a base64 encoded version of the signature to STDOUT and details
+about the signature to STDERR. Note that due to
+<a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug
+in the tsget script</a>, you might need to modify the included script
+and remove the last line. Or just write your own HTTP uploader using
+curl. :) Now you too can prove and verify that files have not been
+changed.</p>
+
+<p>But the Internet need more public trusted timestamp services.
+Perhaps something for <a href="http://www.uninett.no/">Uninett</a> or
+my work place the <a href="http://www.uio.no/">University of Oslo</a>
+to set up?</p>

- <pubDate>Sun, 18 Aug 2013 14:00:00 +0200</pubDate>
- <description><p>Earlier, I reported about
-<a href="http://people.skolelinux.org/pere/blog/How_to_fix_a_Thinkpad_X230_with_a_broken_180_GB_SSD_disk.html">my
-problems using an Intel SSD 520 Series 180 GB disk</a>. Friday I was
-told by IBM that the original disk should be thrown away. And as
-there no longer was a problem if I bricked the firmware, I decided
-today to try to install Intel firmware to replace the Lenovo firmware
-currently on the disk.</p>
-
-<p>I searched the Intel site for firmware, and found
-<a href="https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3472&DwnldID=18363&ProductFamily=Solid-State+Drives+and+Caching&ProductLine=Intel%c2%ae+High+Performance+Solid-State+Drive&ProductProduct=Intel%c2%ae+SSD+520+Series+(180GB%2c+2.5in+SATA+6Gb%2fs%2c+25nm%2c+MLC)&lang=eng">issdfut_2.0.4.iso</a>
-(aka Intel SATA Solid-State Drive Firmware Update Tool) which
-according to the site should contain the latest firmware for SSD
-disks. I inserted the broken disk in one of my spare laptops and
-booted the ISO from a USB stick. The disk was recognized, but the
-program claimed the newest firmware already were installed and refused
-to insert any Intel firmware. So no change, and the disk is still
-unable to handle write load. :( I guess the only way to get them
-working would be if Lenovo releases new firmware. No idea how likely
-that is. Anyway, just blogging about this test for completeness. I
-got a working Samsung disk, and see no point in spending more time on
-the broken disks.</p>

+ <description><p>Keeping your DVD collection safe from scratches and curious
+children fingers while still having it available when you want to see a
+movie is not straight forward. My preferred method at the moment is
+to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
+Hour or other useful players to view the resulting file. This way the
+subtitles and bonus material are still available and using the ISO is
+just like inserting the original DVD record in the DVD player.</p>
+
+<p>Earlier I used dd for taking security copies, but it do not handle
+DVDs giving read errors (which are quite a few of them). I've also
+tried using
+<a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
+and genisoimage</a>, but these days I use the marvellous python library
+and program
+<a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
+written by Bastian Blank. It is
+<a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
+already</a> and the binary package name is python3-dvdvideo. Instead
+of trying to read every block from the DVD, it parses the file
+structure and figure out which block on the DVD is actually in used,
+and only read those blocks from the DVD. This work surprisingly well,
+and I have been able to almost backup my entire DVD collection using
+this method.</p>
+
+<p>So far, python-dvdvideo have failed on between 10 and
+20 DVDs, which is a small fraction of my collection. The most common
+problem is
+<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
+using UTF-16 instead of UTF-8 characters</a>, which according to
+Bastian is against the DVD specification (and seem to cause some
+players to fail too). A rarer problem is what seem to be inconsistent
+DVD structures, as the python library
+<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
+there is a overlap between objects</a>. An equally rare problem claim
+<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
+value is out of range</a>. No idea what is going on there. I wish I
+knew enough about the DVD format to fix these, to ensure my movie
+collection will stay with me in the future.</p>
+
+<p>So, if you need to keep your DVDs safe, back them up using
+python-dvdvideo. :)</p>

- <title>90 percent done with the Norwegian draft translation of Free Culture</title>

- <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/90_percent_done_with_the_Norwegian_draft_translation_of_Free_Culture.html</guid>
- <pubDate>Fri, 2 Aug 2013 10:40:00 +0200</pubDate>
- <description><p>It has been a while since my last update. Since last summer, I
-have worked on a Norwegian
-<a href="http://www.docbook.org/">docbook</a> version of the 2004 book
-<a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig,
-to get a Norwegian text explaining the problems with the copyright
-law. Yesterday, I finally broken the 90% mark, when counting the
-number of strings to translate. Due to real life constraints, I have
-not had time to work on it since March, but when the summer broke out,
-I found time to work on it again. Still lots of work left, but the
-first draft is nearing completion. I created a graph to show the
-progress of the translation:</p>
-
-<p><img width="80%" align="center" src="https://github.com/petterreinholdtsen/free-culture-lessig/raw/master/progress.png"></p>
-
-<p>When the first draft is done, the translated text need to be
-proof read, and the remaining formatting problems with images and SVG
-drawings need to be fixed. There are probably also some index entries
-missing that need to be added. This can be done by comparing the
-index entries listed in the SiSU version of the book, or comparing the
-English docbook version with the paper version. Last, the colophon
-page with ISBN numbers etc need to be wrapped up before the release is
-done. I should also figure out how to get correct Norwegian sorting
-of the index pages. All docbook tools I have tried so far (xmlto,
-docbook-xsl, dblatex) get the order of symbols and the special
-Norwegian letters ÆØÅ wrong.</p>
-
-<p>There is still need for translators and people with docbook
-knowledge, to be able to get a good looking book (I still struggle
-with dblatex, xmlto and docbook-xsl) as well as to do the draft
-translation and proof reading. And I would like the figures to be
-redrawn as SVGs to make it easy to translate them. Any SVG master
-around? There are also some legal terms that are unfamiliar to me.
-If you want to help, please get in touch with me, and check out the
-project files currently available from
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a>.</p>
-
-<p>If you are curious what the translated book currently look like,
-the updated
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>
-and
-<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a>
-are published on github. The HTML version is published as well, but
-github hand it out with MIME type text/plain, confusing browsers, so I
-saw no point in linking to that version.</p>

+ <description><p>Det offentlige Norge har mye kunnskap og informasjon. Men hvordan
+kan en få tilgang til den på en enkel måte? Takket være et lite
+knippe lover og tilhørende forskrifter, blant annet
+<a href="http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven</a>,
+<a href="http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven</a>
+og
+<a href="http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven</a>
+har en rett til å spørre det offentlige og få svar. Men det finnes
+intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
+å måtte forstyrre myndighetene gang på gang for å få tak i samme
+informasjonen på nytt. <a href="http://www.mysociety.org/">Britiske
+mySociety</a> har laget tjenesten
+<a href="http://www.whatdotheyknow.com/">WhatDoTheyKnow</a> som gjør
+noe med dette. I Storbritannia blir WhatdoTheyKnow brukt i
+<a href="http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
+15% av alle innsynsforespørsler mot sentraladministrasjonen</a>.
+Prosjektet heter <a href="http://www.alaveteli.org/">Alaveteli</A>, og
+er takk i bruk en rekke steder etter at løsningen ble generalisert og
+gjort mulig å oversette. Den hjelper borgerne med å be om innsyn,
+rådgir ved purringer og klager og lar alle se hvilke henvendelser som
+er sendt til det offentlige og hvilke svar som er kommet inn, i et
+søkpart arkiv. Her i Norge holder vi i foreningen NUUG på å få opp en
+norsk utgave av Alaveteli, og her trenger vi din hjelp med
+oversettelsen.</p>
+
+<p>Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
+skulle gjerne vært oppe i 100 % før lansering. Oversettelsen gjøres
+på <a href="https://www.transifex.com/projects/p/alaveteli/">Transifex,
+der enhver som registrerer seg</a> og ber om tilgang til
+bokmålsoversettelsen får bidra. Vi har satt opp en test av tjenesten
+(som ikke sender epost til det offentlige, kun til oss som holder på å
+sette opp tjenesten) på maskinen
+<a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der
+en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.
+Når tjenesten lanseres vil den hete
+<a href="https://www.mimesbrønn.no/">Mimes brønn</a>, etter
+visdomskilden som Odin måtte gi øyet sitt for å få drikke i. Den
+nettsiden er er ennå ikke klar til bruk.</p>
+
+<p>Hvis noen vil oversette til nynorsk også, så skal vi finne ut
+hvordan vi lager en flerspråklig tjeneste. Men i første omgang er
+fokus på bokmålsoversettelsen, der vi selv har nok peiling til å ha
+fått oversatt 76%, men trenger hjelp for å komme helt i mål. :)</p>

- <pubDate>Sat, 27 Jul 2013 20:30:00 +0200</pubDate>
- <description><p>The first wheezy based beta release of Debian Edu was wrapped up
-today. This is the release announcement:</p>
-
-<p><strong>New features for Debian Edu 7.1+edu0~b0 released
-2013-07-27</strong></p>
-
-<p>These are the release notes for for Debian Edu / Skolelinux
-7.1+edu0~b0, based on Debian with codename "Wheezy".</p>
-
-<p><strong>About Debian Edu and Skolelinux</strong></p>
-
-<p><a href="http://www.skolelinux.org/">Debian Edu, also known as
-Skolelinux</a>, is a Linux distribution based on Debian providing an
-out-of-the box environment of a completely configured school
-network. Immediately after installation a school server running all
-services needed for a school network is set up just waiting for users
-and machines being added via GOsa², a comfortable Web-UI. A netbooting
-environment is prepared using PXE, so after initial installation of
-the main server from CD, DVD or USB stick all other machines can be
-installed via the network. The provided school server provides LDAP
-database and Kerberos authentication service, centralized home
-directories, DHCP server, web proxy and many other services. The
-desktop contains
-<a href="http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html">more
-than 60 educational software packages</a> and more are available from
-the Debian archive, and schools can choose between KDE, Gnome, LXDE
-and Xfce desktop environment.</p>
-
-<p>This is the fifth test release based on Debian Wheezy. Basically
-this is an updated and slightly improved version compared to the
-Squeeze release.</p>
-
-<p>ALERT: Alpha based installations should reinstall or downgrade the
-versions of gosa and libpam-mklocaluser to the ones used in this beta
-release.</p>

+ <description><p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
+project</a> is working on providing the software and hardware for
+making it easy for non-technical people to host their data and
+communication at home, and being able to communicate with their
+friends and family encrypted and away from prying eyes. It has been
+going on for a while, and is slowly progressing towards a new test
+release (0.2).</p>
+
+<p>And what day could be better than the Pi day to announce that the
+new version will provide "hard drive" / SD card / USB stick images for
+Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
+system), and can also be installed using a Debian installer preseed
+file. The Debian based Freedombox is now based on Debian Jessie,
+where most of the needed packages used are already present. Only one,
+the freedombox-setup package, is missing. To try to build your own
+boot image to test the current status, fetch the freedom-maker scripts
+and build using
+<a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
+with a user with sudo access to become root:
+
+<pre>
+git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
+ freedom-maker
+sudo apt-get install git vmdebootstrap mercurial python-docutils \
+ mktorrent extlinux virtualbox qemu-user-static binfmt-support \
+ u-boot-tools
+make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
+</pre>
+
+<p>Root access is needed to run debootstrap and mount loopback
+devices. See the README for more details on the build. If you do not
+want all three images, trim the make line. But note that thanks to <a
+href="https://bugs.debian.org/741407">a race condition in
+vmdebootstrap</a>, the build might fail without the patch to the
+kpartx call.</p>
+
+<p>If you instead want to install using a Debian CD and the preseed
+method, boot a Debian Wheezy ISO and use this boot argument to load
+the preseed values:</p>
+
+<pre>
+url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
+</pre>
+
+<p>But note that due to <a href="https://bugs.debian.org/740673">a
+recently introduced bug in apt in Jessie</a>, the installer will
+currently hang while setting up APT sources. Killing the
+'<tt>apt-cdrom ident</tt>' process when it hang a few times during the
+installation will get the installation going. This affect all
+installations in Jessie, and I expect it will be fixed soon.</p>
+
+<p>Give it a go and let us know how it goes on the mailing list, and help
+us get the new release published. :) Please join us on
+<a href="irc://irc.debian.org:6667/%23freedombox">IRC (#freedombox on
+irc.debian.org)</a> and
+<a href="http://lists.alioth.debian.org/mailman/listinfo/freedombox-discuss">the
+mailing list</a> if you want to help make this vision come true.</p>

+storing user home directories and data. The design for handling this
+in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
+to update the automount rules in LDAP and let the automount daemon on
+the clients take care of the rest. I was reminded about the need to
+document this better when one of the customers of
+<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
+on the board of directors, asked about how to do this. The steps to
+get this working are the following:</p>
+
+<p><ol>
+
+<li>Add new storage server in DNS. I use nas-server.intern as the
+example host here.</li>
+
+<li>Add automoun LDAP information about this server in LDAP, to allow
+all clients to automatically mount it on reqeust.</li>
+
+<li>Add the relevant entries in tjener.intern:/etc/fstab, because
+tjener.intern do not use automount to avoid mounting loops.</li>
+
+</ol></p>
+
+<p>DNS entries are added in GOsa², and not described here. Follow the
+<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
+in the manual</a> (Machine Management with GOsa² in section Getting
+started).</p>
+
+<p>Ensure that the NFS export points on the server are exported to the
+relevant subnets or machines:</p>
+
+<p><blockquote><pre>
+root@tjener:~# showmount -e nas-server
+Export list for nas-server:
+/storage 10.0.0.0/8
+root@tjener:~#
+</pre></blockquote></p>
+
+<p>Here everything on the backbone network is granted access to the
+/storage export. With NFSv3 it is slightly better to limit it to
+netgroup membership or single IP addresses to have some limits on the
+NFS access.</p>
+
+<p>The next step is to update LDAP. This can not be done using GOsa²,
+because it lack a module for automount. Instead, use ldapvi and add
+the required LDAP objects using an editor.</p>
+
+<p><blockquote><pre>
+ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
+</pre></blockquote></p>
+
+<p>When the editor show up, add the following LDAP objects at the
+bottom of the document. The "/&" part in the last LDAP object is a
+wild card matching everything the nas-server exports, removing the
+need to list individual mount points in LDAP.</p>
+
+<p><blockquote><pre>
+add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: nas-server
+automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+
+add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: top
+objectClass: automountMap
+ou: auto.nas-server
+
+add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
+objectClass: automount
+cn: /
+automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
+</pre></blockquote></p>
+
+<p>The last step to remember is to mount the relevant mount points in
+tjener.intern by adding them to /etc/fstab, creating the mount
+directories using mkdir and running "mount -a" to mount them.</p>
+
+<p>When this is done, your users should be able to access the files on
+the storage server directly by just visiting the
+/tjener/nas-server/storage/ directory using any application on any
+workstation, LTSP client or LTSP server.</p>

+ <title>Hvordan bør RFC 822-formattert epost lagres i en NOARK5-database?</title>

+ <description><p>For noen uker siden ble NXCs fri programvarelisenserte
+NOARK5-løsning
+<a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
+NUUG</a> (video
+<a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
+foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
+standarden for arkivhåndtering i det offentlige Norge. Jeg lurer på
+om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
+av dem er det mest aktuelt å lagre epost. Jeg klarte ikke finne noen
+anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
+burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
+PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
+(eller enda værre, tar papirutskrift og lagrer bildet av eposten som
+PDF i arkivet).</p>
+
+<p>Det er ikke så mange formater som er akseptert av riksarkivet til
+langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
+aktuelle i så måte. Det slo meg at det måtte da finnes en eller annen
+egnet XML-representasjon og at det kanskje var enighet om hvilken som
+burde brukes, så jeg tok mot til meg og spurte
+<a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
+arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
+noen anbefalinger:
+
+<p><blockquote>
+<p>Hei.</p>
+
+<p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
+lurer på om det er definert en anbefaling om hvordan RFC
+822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
+i NOARK5, slik at en bevarer all informasjon i eposten
+(f.eks. Received-linjer). Finnes det en anbefalt XML-mapping ala den
+som beskrives på
+&lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;? Mitt
+mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
+kunne få ut en identisk formattert kopi av opprinnelig epost ved
+behov.</p>
+</blockquote></p>
+
+<p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
+direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
+seniorrådgiver Geir Ivar Tungesvik:</p>
+
+<p><blockquote>
+<p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
+e-post til XML. Det står arkivskaper fritt å eventuelt definere/bruke
+eget format. Inklusive da - som det spørres om - et format der det er
+mulig å re-etablere e-post format ut fra XML-en. XML (e-post)
+dokumenter må være referert i arkivstrukturen, og det må vedlegges et
+gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
+til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
+utrekk ved avlevering til depot.</p>
+
+<p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
+etter dialog med Riksarkivet i forbindelse med godkjenning. For
+offentlige arkiv er det særlig viktig med filene loependeJournal.xml
+og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
+5 standarden er selvsagt frie til å bruke det som er relevant for dem
+av obligatoriske krav.</p>
+</blockquote></p>
+
+<p>Det ser dermed ut for meg som om det er et lite behov for å
+standardisere XML-lagring av RFC-822-formatterte meldinger. Noen som
+vet om god spesifikasjon i så måte? I tillegg til den omtalt over,
+har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822

- <description><p>Today I switched to
-<a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">my
-new laptop</a>. I've previously written about the problems I had with
-my new Thinkpad X230, which was delivered with an
-<a href="http://people.skolelinux.org/pere/blog/Intel_SSD_520_Series_180_GB_with_Lenovo_firmware_still_lock_up_from_sustained_writes.html">180
-GB Intel SSD disk with Lenovo firmware</a> that did not handle
-sustained writes. My hardware supplier have been very forthcoming in
-trying to find a solution, and after first trying with another
-identical 180 GB disks they decided to send me a 256 GB Samsung SSD
-disk instead to fix it once and for all. The Samsung disk survived
-the installation of Debian with encrypted disks (filling the disk with
-random data during installation killed the first two), and I thus
-decided to trust it with my data. I have installed it as a Debian Edu
-Wheezy roaming workstation hooked up with my Debian Edu Squeeze main
-server at home using Kerberos and LDAP, and will use it as my work
-station from now on.</p>
-
-<p>As this is a solid state disk with no moving parts, I believe the
-Debian Wheezy default installation need to be tuned a bit to increase
-performance and increase life time of the disk. The Linux kernel and
-user space applications do not yet adjust automatically to such
-environment. To make it easier for my self, I created a draft Debian
-package <tt>ssd-setup</tt> to handle this tuning. The
-<a href="http://anonscm.debian.org/gitweb/?p=collab-maint/ssd-setup.git">source
-for the ssd-setup package</a> is available from collab-maint, and it
-is set up to adjust the setup of the machine by just installing the
-package. If there is any non-SSD disk in the machine, the package
-will refuse to install, as I did not try to write any logic to sort
-file systems in SSD and non-SSD file systems.</p>
-
-<p>I consider the package a draft, as I am a bit unsure how to best
-set up Debian Wheezy with an SSD. It is adjusted to my use case,
-where I set up the machine with one large encrypted partition (in
-addition to /boot), put LVM on top of this and set up partitions on
-top of this again. See the README file in the package source for the
-references I used to pick the settings. At the moment these
-parameters are tuned:</p>

-<p>During installation, I cancelled the part where the installer fill
-the disk with random data, as this would kill the SSD performance for
-little gain. My goal with the encrypted file system is to ensure
-those stealing my laptop end up with a brick and not a working
-computer. I have no hope in keeping the really resourceful people
-from getting the data on the disk (see
-<a href="http://xkcd.com/538/">XKCD #538</a> for an explanation why).
-Thus I concluded that adding the discard option to crypttab is the
-right thing to do.</p>
-
-<p>I considered using the noop I/O scheduler, as several recommended
-it for SSD, but others recommended deadline and a benchmark I found
-indicated that deadline might be better for interactive use.</p>
-
-<p>I also considered using the 'discard' file system option for ext3
-and ext4, but read that it would give a performance hit ever time a
-file is removed, and thought it best to that that slowdown once a day
-instead of during my work.</p>
-
-<p>My package do not set up tmpfs on /var/run, /var/lock and /tmp, as
-this is already done by Debian Edu.</p>
-
-<p>I have not yet started on the user space tuning. I expect
-iceweasel need some tuning, and perhaps other applications too, but
-have not yet had time to investigate those parts.</p>
-
-<p>The package should work on Ubuntu too, but I have not yet tested it
-there.</p>
-
-<p>As for the answer to the question in the title of this blog post,
-as far as I know, the only solution I know about is to replace the
-disk. It might be possible to flash it with Intel firmware instead of
-the Lenovo firmware. But I have not tried and did not want to do so
-without approval from Lenovo as I wanted to keep the warranty on the
-disk until a solution was found and they wanted the broken disks
-back.</p>

- <description><p>A few days ago, I wrote about
-<a href="http://people.skolelinux.org/pere/blog/The_Thinkpad_is_dead__long_live_the_Thinkpad_X230_.html">the
-problems I experienced with my new X230 and its SSD disk</a>, which
-was dying during installation because it is unable to cope with
-sustained write. My supplier is in contact with
-<a href="http://www.lenovo.com/">Lenovo</a>, and they wanted to send a
-replacement disk to try to fix the problem. They decided to send an
-identical model, so my hopes for a permanent fix was slim.</p>
-
-<p>Anyway, today I got the replacement disk and tried to install
-Debian Edu Wheezy with encrypted disk on it. The new disk have the
-same firmware version as the original. This time my hope raised
-slightly as the installation progressed, as the original disk used to
-die after 4-7% of the disk was written to, while this time it kept
-going past 10%, 20%, 40% and even past 50%. But around 60%, the disk
-died again and I was back on square one. I still do not have a new
-laptop with a disk I can trust. I can not live with a disk that might
-lock up when I download a new
-<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a> ISO or
-other large files. I look forward to hearing from my supplier with
-the next proposal from Lenovo.</p>
-
-<p>The original disk is marked Intel SSD 520 Series 180 GB,
-11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW:

-<p>The only difference is in the first number (serial number?), ISN,
-SA, date and WNPP values. Mentioning all the details here in case
-someone is able to use the information to find a way to identify the
-failing disk among working ones (if any such working disk actually
-exist).</p>

- <title>The Thinkpad is dead, long live the Thinkpad X230?</title>

- <description><p>Half a year ago, I reported that I had to find a
-<a href="http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html">replacement
-for my trusty old Thinkpad X41</a>. Unfortunately I did not have much
-time to spend on it, and it took a while to find a model I believe
-will do the job, but two days ago the replacement finally arrived. I
-ended up picking a
-<a href="http://www.linlap.com/lenovo_thinkpad_x230">Thinkpad X230</a>
-with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as
-a roaming workstation, and it seemed to work flawlessly. But my
-second installation with encrypted disk was not as successful. More
-on that below.</p>
-
-<p>I had a hard time trying to track down a good laptop, as my most
-important requirements (robust and with a good keyboard) are never
-listed in the feature list. But I did get good help from the search
-feature at <a href="http://www.prisjakt.no/">Prisjakt</a>, which
-allowed me to limit the list of interesting laptops based on my other
-requirements. A bit surprising that SSD disk are not disks according
-to that search interface, so I had to drop specifying the number of
-disks from my search parameters. I also asked around among friends to
-get their impression on keyboards and robustness.</p>
-
-<p>So the new laptop arrived, and it is quite a lot wider than the
-X41. I am not quite convinced about the keyboard, as it is
-significantly wider than my old keyboard, and I have to stretch my
-hand a lot more to reach the edges. But the key response is fairly
-good and the individual key shape is fairly easy to handle, so I hope
-I will get used to it. My old X40 was starting to fail, and I really
-needed a new laptop now. :)</p>
-
-<p>Turning off the touch pad was simple. All it took was a quick
-visit to the BIOS during boot it disable it.</p>
-
-<p>But there is a fatal problem with the laptop. The 180 GB SSD disk
-lock up during load. And this happen when installing Debian Wheezy
-with encrypted disk, while the disk is being filled with random data.
-I also tested to install Ubuntu Raring, and it happen there too if I
-reenable the code to fill the disk with random data (it is disabled by
-default in Ubuntu). And the bug with is already known. It was
-reported to Debian as <a href="http://bugs.debian.org/691427">BTS
-report #691427 2012-10-25</a> (journal commit I/O error on brand-new
-Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux
-kernel developers as
-<a href="https://bugzilla.kernel.org/show_bug.cgi?id=51861">Kernel bugzilla
-report #51861 2012-12-20</a> (Intel SSD 520 stops working under load
-(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
-Lenovo forums, both for
-<a href="http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549">T430
-2012-11-10</a> and for
-<a href="http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147">X230
-03-20-2013</a>. The problem do not only affect installation. The
-reports state that the disk lock up during use if many writes are done
-on the disk, so it is much no use to work around the installation
-problem and end up with a computer that can lock up at any moment.
-There is even a
-<a href="https://git.efficios.com/?p=test-ssd.git">small C program
-available</a> that will lock up the hard drive after running a few
-minutes by writing to a file.</p>
-
-<p>I've contacted my supplier and asked how to handle this, and after
-contacting PCHELP Norway (request 01D1FDP) which handle support
-requests for Lenovo, his first suggestion was to upgrade the disk
-firmware. Unfortunately there is no newer firmware available from
-Lenovo, as my disk already have the most recent one (version LF1i). I
-hope to hear more from him today and hope the problem can be
-fixed. :)</p>
